| الوصف: | International audience ; The use of biobased materials in building construction is increasingly recommended because they have a low environmental impact and allow the re-duction of fossil resources and energy consumption. Among biobased materials, hemp lime concrete (HLC) which has high insulation capacity was investigated in many studies highlighting its capacity to regulate interior relative humidity and pollutant. In order to design high-performance biobased concretes, a new hemp lime concrete incorporating micro-capsulated phase change material (HLC-PCM) was developed. The materials studied combine the hygric regulation capacity of HLC with the thermal regulation performance of PCM. This article presents hygric properties of three HLC-PCM formulations. The previous studies showed that the thermal conductivity remains low, the heat capacity and thermal inertia increase considerably for hemp concrete with PCM. In this article, the sorption isotherm curves of studied materials were obtained by measuring the moisture content of test samples according to NF EN ISO 12571. Regarding the moisture buffering capacity, it was carried out according to the NORDTEST method. For the three studied composites, the results obtained are consistent with the ones found in the literature. It is shown that these materials are hygroscopic and have good or excellent moisture buffering capacity. |
